This invention relates particularly to duplicating machines of the typein which the paper webs are carried over a. flat platen mounted betweenrails which support a type-' writing machine, which co-operates with theplaten. I

The primary object is to provide improved mechanism adapted to severpaper webs which have been drawn over the platen.

The present application constitutes a division of my application SerialNo. 391,207, filed September 9, 1929.

The invention is illustrated in a preferred embodiment in theaccompanying drawings,

in which- Figure 1 is a side elevational view of a.

duplicating machine embodying the inven tion; Fig. 2, a broken plan viewof the platen and cutting mechanism; Fig. 8, a broken longitudinalvertical sectional view taken as indicated at line 3 of Fig. 2; Fig. 4,a similar view showing the blade after it has severed the webs, taken asindicated at line 4: of Fig. 2; and Fig. 5, a perspective view on anenlarged scale showing the cutting blade.

In the preferred embodiment illustrated, A designates a frame comprisinga standard A and a surmounting horizontally disposed bed A B, a platenmounted in the front portion of the bed; 0, a typewriting machine onrails which form the main portion of the bed; D, web-control-mechanismmounted in the rear portion of the bed A and E, webcutting mechanismmounted on the front portion of the bed A The duplicating machinecomprising the frame A and the typewriter C mounted thereon are ofwell-known construction. The typewriter is mounted on longitudinal rails1, having rearward extensions, or arms, 1? between which the demountabledevice D is supported. As shown in Figs. 3 and 4:, the rails orlongitudinal members are connected at their front ends by a cross-bar 2,which is equipped with pins or hooks 3 adapted to engage registerperforations with which the multiple strips of paper are provided.

The platen B is mounted in a manner usual in this type of machine. It isnormally held ed on a pivot 9 carried by fixed arms 10 which pro ectfrom a cross-bar or rod 11, which connects the members of thestandard Anear their lower ends. a

The mechanism4 also includes a rock-shaft 12 having fixedly securedthereto bent arms 13 which are connected at their free ends by aclamping-bar 14 which constitutes also one ofa pair of shear-members.The bar 14 is provided with perforations 14 which accommodate the hooks3 when the bar is in clamping position. I

The typewriter O is capable of being moved forwardly and rearwardly .onthe track for line-spacing, and is capable of being fed transversely inthe typing operation.

The web-control mechanism D is described in detail in my co-pendingapplication Serial No. 391,207.

The cutter mechanism E comprises a rotatable shear-member 15 whichco-acts with the shear-member 14. The shear-member 15v is provided withtrunnions 16 which are j ournaled in bearings 17 with which the frontends of the member 1 are equipped. An op-. erating handle 18 is providedto rock the shear-member 15 and is held upraised normally by a spring 19which is kept in position by an arcuate arm 20 passing through the coilof the spring. The shear-member 15 has a shearing-edge 15which,'pr'eferably, has a high point at the center and tapers in bothdirections therefrom, so that when the paper is sheared it is firstpierced at the center and then sheared in both directions therefrom. d I

The foregoing detailed description has been given for clearness ofunderstanding only,

with alever (iwhich is connected by a link 7 V and no unnecessarylimitations should be" ing means mounted on said frame in front of theplaten and adapted to grip webs led 7 over said platen; and a rotatableshear-member adapted to co-act with said clamping means to severwebsheld' by the. clamping means." 7
